The example above selects unconditional tripping for assertion of the Zone 1 phase and
ground distance elements, Zone 2 and Zone 3 time delayed phase and ground distance
elements, instantaneous and inverse-time residual overcurrent elements, high-set nondirection-
al phase overcurrent element, or the IN1 programmable input.
Note:
The masks must be properly configured for your application.
The programmable masks enable the outputs to be used for any desired function. Examples
include separating outputs for phase and ground, or by direction or by zone.
OPEN
The TRIP output relay closes in response to the OPEN command. The TRIP relay remains
closed until the 50NG and 46QL overcurrent elements have dropped out. In all cases the
TRIP output remains asserted at least TDUR cycles. If TDUR=0, the OPEN command is
aborted.
To open the power circuit breaker by command, type
OPEN <ENTER>.
The prompt
"Open BREAKER (Y/N)?" is transmitted. Answering
Y <ENTER>
yields a second
prompt: "Are you sure (Y/N)?
"
Answering
Y <ENTER>
again closes the TRIP output
relay as described above.
Install jumper JMP104 to enable the OPEN command.
PASSWORD (1 or 2) password
PASSWORD allows you to inspect or change existing passwords. To inspect passwords, type
PASSWORD <ENTER>
